FLUSH-TANK COVER.

1 030,059 Specification of Letters Patent.

Patented-June 18, 19112. Application filed April 16, 1910. Serial No.555,956.

To all whom it may concern Be it known that we, SAMUEL DRUGAN and JOHNSoHonNTHALnR, citizens of the United States, and residents. of Trenton,Mercer county, New Jersey, have invented certain Improvements inFlush-Tank Gov-v ers, of which the following is a specification.

ur invention relates to water closet flush tanks, and the object of ourinvention is to provide an improved form of top or cover, preferablymade of vitreous or earthen ware for use with tanks made of the same orsimilar material.

The present practice, or a practice which has come very much into vogueof late, is to have a tank of the same material as the closet bowl. Inorder to provide a cover for such tank, the material of which it iscomposed demands that it be made sutficiently heavy, to avoid breakageby accident or during the burning operation on the one hand, and so thatit may be retained in place by its own weight on the other hand,

The upper and lower walls may be merged at the front and sides into anornamental edge 5. pper wall may be molded wlnle plastic by suitablemeans in one piece, and the bottom or lower wall may also be moldedwhile plastic in one piece and joined to the upper wall or section, andthese two sections are secured together while in the low space duringthe burning operation, a pair of such aperdesigned, and a number of thesame can be formed in the lower wall without affecting the strength ofthe same or the top or cover.

In order that the top may rest upon and be retained by the wall of theflush tank, we prefer to provide it with a depending edge 9 at thefront, and set inwardly some insure the bur g sired extent withoutdistortion or other damage before or immediately after being taken fromthe kiln.

Our improved top advantage of which duce the dead weight or cover ishollow; the construction is to reof the same and at the same timeprovide a structure possessing all of the features that are desirablefor the purpose for which it is intended. We are further enabled toincrease the strength of the top or cover and prevent distortion of thesame; such distortion beingcaused by the contraction which occurs duringthe burning operation.

ur invention is fully shown in the accompanying drawings, in which:

Figure 1, is a perspective view of our improved tank top or cover shownin the a port-ion of the tank being lndlcated by dotted lines; Fig. 2,is a rear that a continuous projection paralleling the edge may take theplace of such lugs.

It is desirable, of course, in the finishing of such a structure thatthe rear edge or wall bear a definite relation to the front edge of thesame as regards distance from and that it be substantially paralleltherewith. To produce this result, it frequently becomes desirable togrind such rear edge or wall. To this end, the rear edge or wall ishollowed in the manner indicated at 7 so that if such grinding operationbecomes necessary, the portion of the wall to be reduced will berelatively small in area.

Flush tank tops or covers are usually made of white porcelain, but itwill be understood plan view, and Fig. 5, the line a-a, Fig. 3.

In the drawings herewith, 1 represents the top or cover, the uppersurface of which may be ornamental in character or not as desired; whichcover is composed of upper and lower walls 2 and 3, and a rear wall 4.

wall merging with the bottom wall at the "frontand ends of the same.

8. A hollow cover having top, bottom and rear walls integrally connectedtogether, the bottom wall having a dependingedge following the contourof the front and ends of the structure, and the bottom wall having adepending portion affording positioning means for said cover. 1

In testimony whereof, we have signed our names to this specification, inthe presence of two subscribing witnesses.

that other materials may be employed, and that they may be of anornamental character, or not, as may be desired.

We claim:

1. A hollow cover having top, bottom and rear walls integrally connectedtogether, the bottom wall having a depending edge -fo1- lowing thecontour of the front and ends of the structure, and the rear wall havinga portion of its surface cut away.

2. A hollow cover having top, bottom andrear walls integrally connectedtogether, the bottom wall having a depending edge following the contourof the front and ends of the structure and a plurality of lugsparalleling said depending edge to afford positioning means for saidcover, and the top Copies of this patent may be obtained for five centseach, by addressing the Commissioner of Patents,
